| Abstract | A study was made to find an expression for the Class "A" Pan
evaporation as a function of Piche evaporation, air vapor flux
deficit, and other weather parameters by a multiple regression analysis of daily meteorological observations at Bangkok Station from 1963 to 1967. Results of the regression analysis showed that the ratio of daily pan evaporation to minimum daily relative humidity
(EPA/RHMIN) could be related (R = 0.86) to Piche evaporation (EPI),air vapor flux deficit (AVF ), solar radiation (ERAD), wind at pan level (WPAN), and daily maximum temperature (TMAX). From this ratio daily pan evaporation can be evaluated. The regression equation is
given below:
EPA
RHMIN = 0.028 + 0.008 x EPI + 0.002 x AVFD + 0.003 x ERAD
- 0.011 x WPAN- 0.0015 x TMAX
Other equation were also developed for stations having limited observations. The relationship developed could be used in a tropical region. A tropical region is defined as shown on the map in Appendix
